An attacker could exploit this vulnerability by sending a crafted MPLS echo-request to an IP address on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a device reload and a DoS condition."}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-moam-rce-uBTzYV7","name":"cisco-sa-moam-rce-uBTzYV7"}],"exploits":[{"lang":"en","value":"The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory."}],"source":{"advisory":"cisco-sa-moam-rce-uBTzYV7","discovery":"INTERNAL","defects":["CSCwu19799"]},"problemTypes":[{"descriptions":[{"lang":"en","description":"Free of Memory not on the Heap","type":"cwe","cweId":"CWE-590"}]}],"affected":[{"vendor":"Cisco","product":"Cisco NX-OS Software","versions":[{"version":"9.3(2)","status":"affected"},{"version":"9.3(1)","status":"affected"},{"version":"9.3(1z)","status":"affected"},{"version":"9.3(3)","status":"affected"},{"version":"9.3(4)","status":"affected"},{"version":"9.3(5)","status":"affected"},{"version":"9.3(6)","status":"affected"},{"version":"9.3(5w)","status":"affected"},{"version":"9.3(7)","status":"affected"},{"version":"9.3(7k)","status":"affected"},{"version":"9.3(7a)","status":"affected"},{"version":"9.3(8)","status":"affected"},{"version":"9.3(9)","status":"affected"},{"version":"9.3(10)","status":"affected"},{"version":"10.3(1)","status":"affected"},{"version":"10.3(2)","status":"affected"},{"version":"9.3(11)","status":"affected"},{"version":"10.3(3)","status":"affected"},{"version":"9.3(12)","status":"affected"},{"version":"10.4(1)","status":"affected"},{"version":"10.3(99w)","status":"affected"},{"version":"10.3(3w)","status":"affected"},{"version":"10.3(99x)","status":"affected"},{"version":"10.3(3o)","status":"affected"},{"version":"10.3(4)","status":"affected"},{"version":"10.3(3p)","status":"affected"},{"version":"10.3(4a)","status":"affected"},{"version":"10.4(2)","status":"affected"},{"version":"10.3(3q)","status":"affected"},{"version":"9.3(13)","status":"affected"},{"version":"10.3(5)","status":"affected"},{"version":"10.4(3)","status":"affected"},{"version":"10.3(3x)","status":"affected"},{"version":"10.3(4g)","status":"affected"},{"version":"10.5(1)","status":"affected"},{"version":"10.3(3r)","status":"affected"},{"version":"10.3(6)","status":"affected"},{"version":"9.3(14)","status":"affected"},{"version":"10.4(4)","status":"affected"},{"version":"10.3(4h)","status":"affected"},{"version":"10.5(2)","status":"affected"},{"version":"10.3(7)","status":"affected"},{"version":"10.4(5)","status":"affected"},{"version":"10.5(3)","status":"affected"},{"version":"9.3(15)","status":"affected"},{"version":"10.4(4g)","status":"affected"},{"version":"10.5(4)","status":"affected"},{"version":"10.6(1)","status":"affected"},{"version":"10.5(3t)","status":"affected"},{"version":"10.3(8)","status":"affected"},{"version":"10.4(6)","status":"affected"},{"version":"10.5(3s)","status":"affected"},{"version":"10.5(3e)","status":"affected"},{"version":"10.5(3o)","status":"affected"},{"version":"9.3(16)","status":"affected"},{"version":"10.6(1s)","status":"affected"},{"version":"10.6(2)","status":"affected"},{"version":"10.5(3p)","status":"affected"},{"version":"10.3(9)","status":"affected"},{"version":"10.6(2s)","status":"affected"},{"version":"10.6(3)","status":"affected"},{"version":"10.4(7)","status":"affected"},{"version":"10.5(5)","status":"affected"},{"version":"9.3(17)","status":"affected"},{"version":"10.6(2n)","status":"affected"},{"version":"10.6(3s)","status":"affected"}],"defaultStatus":"unknown"}],"providerMetadata":{"orgId":"d1c1063e-7a18-46af-9102-31f8928bc633","shortName":"cisco","dateUpdated":"2026-10-07T16:14:26.107Z"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-07T00:00:00+00:00","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3","id":"CVE-2026-76465"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-08T03:55:35.639Z"}}]}}
